Anthurium plant named ‘ANTHDASYM’

ABSTRACT

A new and distinct variety of  Anthurium  plant named ‘ANTHDASYM’ particularly distinguished by having dark red, heart-shaped, cupped and very durable spathes that retain the original color for very long periods of time, green, long cordate, durable leaves, rich shoot formation, rich flowering continuously throughout the year, a compact and full plant habit and a plant height of 30 cm to 35 cm, is disclosed.

Genus and species: Anthurium andreanum L.

Variety denomination: ‘ANTHDASYM’.

BACKGROUND OF THE NEW PLANT

The present invention comprises a new and distinct variety of Anthurium, botanically known as Anthurium andreanum L., and hereinafter referred to by the variety name ‘ANTHDASYM’. The new variety originated from a hybridization made in December 2006 in Bleiswijk, The Netherlands. The female parent was a red Anthurium pot plant designated ‘8477-02’ (unpatented), and the male parent was a red Anthurium plant designated ‘9863-02’ (unpatented).

A single plant was selected in April 2008 and has been asexually reproduced repeatedly by tissue culture in Bleiswijk, The Netherlands over a seven-year period. The present invention has been found to retain its distinctive characteristics through successive asexual propagations.

Plant Breeder's Rights for this variety have been applied for in the European Union on Jul. 5, 2013 and in Mexico on Aug. 4, 2015. ‘ANTHDASYM’ has not been made publicly available or sold anywhere in the world more than one year prior to the filing of this application.

SUMMARY OF THE INVENTION

The following are the most outstanding and distinguishing characteristics of this new variety when grown under normal horticultural practices in Bleiswijk, The Netherlands:

-   -   1) Large bright red cordate spathe;     -   2) Short white spadix with yellow-green tip;     -   3) Compact plant habit with some shoots; and     -   4) Dark green, long cordate leaves.

DESCRIPTION OF THE PHOTOGRAPHS

This new Anthurium plant is illustrated by the accompanying photographs which show the overall plant habit including blooms and foliage of the plant; the colors shown are as true as can be reasonably obtained by conventional photographic procedures. The photographs are of a 35-week old plant grown in a greenhouse in Bleiswijk, The Netherlands in July 2015.

FIG. 2 shows a close-up of the mature spathe.

FIG. 3 shows the upper leaf blade surface.

DESCRIPTION OF THE NEW VARIETY

The following detailed description sets forth the distinctive characteristics of ‘ANTHDASYM’. The data which define these characteristics were collected from asexual reproductions carried out in Bleiswijk, The Netherlands. The plant history was taken on 35-week old plants which were planted from tissue culture in 14-centimeter pots and grown in a glass greenhouse between 19° C. and 24° C. Observations were made in July 2015. Color readings were taken under 5000 lux natural light in the greenhouse. Color references are primarily to The R.H.S. Colour Chart of The Royal Horticultural Society of London (R.H.S.) (2001).

COMPARISON WITH PARENTAL AND COMMERCIAL VARIETIES

‘ANTHDASYM’ differs from the female parent plant ‘8477-02’ (unpatented) in that ‘ANTHDASYM’ has a light green leaf color, whereas ‘8477-02’ has a more dark green leaf color. Additionally, ‘ANTHDASYM’ has a shorter spadix than ‘8477-02’.

‘ANTHDASYM’ differs from male parent plant ‘9863-02’ (unpatented) in that ‘ANTHDASYM’ has a dark red spathe, whereas ‘9863-02’ has a more bright red spathe. Additionally, ‘ANTHDASYM’ has a shorter spadix than ‘9863-02’.

‘ANTHDASYM’ differs from commercial variety ‘ANTHOLODOJ’ (U.S. Plant Pat. No. 20,254) in that ‘ANTHDASYM’ has non-touching lobes of the spathe and a long cordate leaf shape, whereas ‘ANTHOLODOJ’ has touching lobes of the spathe and a more broad cordate leaf shape. Additionally, the angle between spadix and peduncle of ‘ANTHDASYM’ is much larger than that of ‘ANTHOLODOJ’.

‘ANTHDASYM’ differs from commercial variety ‘ANTHCITOK’ (unpatented) in that ‘ANTHDASYM’ has a dark red spathe, whereas ‘ANTHCITOK’ has a more bright red spathe. Additionally, the spadix length of ‘ANTHDASYM’ is shorter than that of ‘ANTHCITOK’ and the angle between spadix and peduncle of ‘ANTHDASYM’ is slightly smaller than that of ‘ANTHCITOK’. 

I claim:
 1. A new and distinct variety of Anthurium plant named ‘ANTHDASYM’, substantially as illustrated and described herein.
